5 RAIN-DUMPING END'GALTE FOR GRAIN WAGONS.

Application filed June 28, 1926. Serial No. 119,121. 7

My invention relates to end gates for grain wagons and'particularly to atype of grain wagon that is commonly used for carrying grain toelevators and 'the like where grain is commonly hauled and dumped intobins; an object being in this device, particularly to provide a graindumping end gate which will not only hold the grainsecurely whenclosedbut also make it possible to very easily limit the flow of grainfrom the wagon when dumpingthe grain into a bin or elevator or the like.7 7

A particular object of'my invention is to provide an end gate for grainwagons that may be easily adjusted into operative position andsubstantially held in such position; and when in operation beconveniently and easily controlled in the normal flow of grain from agrain wagon.

A furtherobject of my invention is to provide'in an end gate for grainwagons a device that may be economically manufactured and simple tooperate.

I attain theobject'of my invention in the device described in theannexed specification, recited in the claims and illustrated in theaccompanying drawing in which like reference numerals indicatelike partsin the several figures.

Referring to the figures:

Figure 1 is an elevation of the graincontrol end'gate of. my inventionshown ina closed position.

Figure 2 is an elevation of my end gate shown in an opened position inwhich positionthe closure members are held to a position of substantialengagement by a latch member adapted to hold the'end' gate closuremembers within predetermined open limits.

Figure 3 is a top view of the end gate shown. in the same open positionas is illustrated in Figure 2.

Referring in detail to the numerals in the several figures, I provide alatch member --1 pivotally attached to a supporting bracket 2 by a pivotpin 3 supported on a closure member -4 and said latch member 1 isattached to extend across closure member 4- and closure member -5-.

It will be observed that latch member,

1 has at each end a stop member designated by numerals '-6 and '7respectively. These two Stop members each have At corresponding endsof'latch member -1 are integral tongues l1 and 12 andtongue '11 isadapted to be held snugly by loclcmember -10 when latch member 1-- is innormally closed posltion while tongue -12- isadapted to slidably movelongitudinallyacross supporting bracket and become engaged by keeper--8', as it moves in behindit when looking closure members 4 and"-5'.Numeral '1l.indicates the strap about hinge pin 32.

Plate 15. normally guides tongue 12 behind the keeper -8. Bracket 2normally supports latch member 1 0n pivot 3- and also pivotally supportslock 10- at pivot 16 while an integral stop member 17+, is made toprotrudev from surface 18. of'bracket 2'' to an extent that will make itnecessary to slidably lift lock member 10 when releasing latch member 1by pulling on handle -19of lock member 10 so as to be able to pivotallyrotate lock member 10 on point -16- so that the handle 19 ther7eof slipsover the top of protruding knob 1 7 It will be seen, therefore, thatwhen lock member 10 is held in a locked osition as is shown in Figure 1,that protru ing lug 17 provides a stop member for handle 19 of lock -10preventing the same from rotating to an unlocked position.

When the closure members t and 5 are tightly closed stop member 20 Willsomewhat overlap on closure member 4- and prevent the loss of grain whenthe closure members arein a closed position.

When mounting the end-gate of my invention into operative position nut-21- is released permitting the frame or brace mem ber composed ofboards --2Q- and 2- hing'cdly connected by hinge 24s-, to he hingedlybroken in which position the endgate is inserted between upright lugs-25 and 26* on one side and -ZT and -2S on the other side of the rearend of a wagon bed designated by numerals -29 and -30 on correspondingsides; and atter the imright hinge pins -31- and I-3:Z- are snuglyadjust-ed between said cleats then nut -f2'1- is screwed up tight afterbrace member -33- is slipped over bolt 34-, thus holding;- the end-gateto operative position.

\Vhcn closing closure members and -5-----; the operator will push in oneach closure member toward the closed position causing latch member l-,which is pivoted on pivot pin 3, to slidably more over supportingbracket -1l toward its position of rest where tongue -l2 o'l latchmember 1- engaged behind keeper 8. As closure members 4 and 5 rotate toclosed position, guide bracket J- guides the latch 1 to its closedposition where it rests upon su 'iport rg bracket *2 and 1s locked inits closed position by lock member -lO-- as described.

To those who are skilled in the art to which this device pertains, itwill be evident that certain minor changes may be made in the details ofthis device and still stay within the spirit and scope of thisinvention; but the preferred arrangement has been herein above describedand illustrated in the drawinns.

Having thus described the nature of my invention. what I claim as newand useful and desire to secure by Letters Patent is:

1. In a grain dumping); end gate of the character described having; aframe member with upright hinge pins and a pair of closure members, alock member comprising in rmtflacrative combination, a sliding latch, abracket supported on one of said closure members for the pivotal supportof said latch nearer one end than the other, a bracket support for saidlatch on the other of said closure members; a limiting bracket forproviding a predetermined open limit for said closure members; saidlatch member cmnprising an angle bar having an upright and a. horizontaltare, said horizontal face turned up at each end; a pivotally mountedlock member for said latch positioned at one end thereof and secured tosaid pivot mounting bracket, an engaging bracket member for slid-ablyengaging the end of said latch member opposite said lock member; wherebysaid closure members may be securely held together to prevent loss ofgrain in wagons and when opened held into a predetermined open limit.

2. In a grain control end gate of the character described having a framemember and a pair of closure members hingetlly connected therewith, alatch comprising in coml'iination, a latch member pivot-ally mountdadjacentthe tree end of one of said closure memi -nrsn a pivotsupporting bracket therefor on said c o -rnre member, a brachet iiorslidably s 'pporti ig said latch member secured to the of her on" s iidclosure n'ieinbcrs and adapted to guide and support the free end of saidlatch memheixa cooperating guide bracket on said latter closure member,positioni-ul to hold said latch member in constant slida-ble engagementwith said closure member; said latch member providhd at each end with anintegral tongue for a latch and a turned up flange as a stopmember;pivoted lock means for holding said latch member in lockedposition; whereby said latch member may securely hold said closuremembers within a predetermined optional position of adjustment for thecontrol of the release of grain from a wagon to whichit is adapted to besecured. y

In witness whereoi, I hereunto set my hand this 31 day of May, A. D.1926.
